[0001] This utility model relates to the field of assembly mechanism technology, and in particular to an automated assembly mechanism for injection molded part winding reels. Background Technology
[0002] With the rapid development of modern industrial automation technology, the demand for efficient and precise automated equipment in injection molding and assembly is increasing. In injection molding production, the winding reel, as a widely used basic component, typically involves multiple complex processes in its assembly, including positioning, gripping, rotating, screw tightening, and material picking. Traditional winding reel assembly methods rely heavily on manual or semi-automated mechanical devices. While this approach meets production needs to some extent, its limitations are becoming increasingly apparent as manufacturing moves towards intelligence and flexibility. In recent years, scholars and companies both domestically and internationally have conducted extensive research on automated injection molding assembly technology, proposing various solutions based on robots, servo drives, and visual recognition. These technological advancements have significantly improved production efficiency and product consistency; however, many problems still remain to be solved in existing technologies.
[0003] Currently, automated assembly equipment for injection molded part winding reels generally suffers from the following shortcomings: most equipment lacks flexible rotation and pressure control functions, making it difficult to adapt to the rapid switching requirements of winding reels of different specifications; existing technologies lack efficient coordination capabilities in material gripping and screw tightening processes, resulting in low overall assembly efficiency. These problems severely restrict the further promotion and application of automated assembly technology for injection molded part winding reels. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automated assembly mechanism for injection molded part winding reels, including a suction cup device. A positioning column is rotatably connected to the center of the suction cup device via a pressure bearing. A hydraulic cylinder is mounted on the upper part of the positioning column, with its piston rod fixedly connected to the positioning column. A screw conveyor for driving the movement of the hydraulic cylinder is mounted on the upper part of the hydraulic cylinder. A first gear is fixedly connected to the outer ring of the pressure bearing. A stepper motor is fixedly connected to the positioning column, and a second gear is fixedly connected to the output shaft of the stepper motor. An electric screwdriver and a material suction device are mounted on the suction cup device.
[0005] The suction cup device has a suction cup hole at its lower part, a winding disc cover at its lower part, a winding disc cylinder at its lower part, a positioning block and a central cylinder fixedly connected to the upper part of the winding disc cylinder, and a screw hole on the winding disc cylinder.
[0006] The electric screwdriver has a motor inside, and the lower end of the motor's output shaft is fixedly connected to a screwdriver bit. The suction cup device has a through hole.
[0007] The suction device includes a negative pressure air pump, and a suction head is connected to the lower part of the negative pressure air pump.
[0008] A camera is mounted on the suction cup device, and a slider is fixedly connected to the upper part of the hydraulic cylinder.
[0009] The lead screw conveying device includes a lead screw, which is connected to a slider via a lead screw nut, and a DC motor is connected to one end of the lead screw.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by designing the center of the suction cup device to be rotatably connected to the positioning column through a pressure bearing, and using a hydraulic cylinder to drive the positioning column to move up and down, the efficient and precise assembly of the winding reel cover and the winding reel cylinder is achieved.
[0011] The introduction of pressure bearings allows the suction cup device to maintain stable grip while allowing the winding reel to rotate freely around the positioning post.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-6 An automated assembly mechanism for injection molded part winding spools is shown, including a suction cup device 6. The lower part of the suction cup device 6 is provided with a suction cup hole 61 for picking up the winding spool cover 1 and placing it above the winding spool cylinder 2.
[0023] The center of the suction cup device 6 is rotatably connected to the positioning column 21 via the pressure bearing 13. The upper part of the positioning column 21 is equipped with a hydraulic cylinder 8. The piston rod of the hydraulic cylinder 8 is fixedly connected to the positioning column 21, thereby driving the positioning column 21 to move up and down.
[0024] The upper part of the hydraulic cylinder 8 is provided with a screw conveyor device 19 for driving its movement. The screw conveyor device 19 includes a screw 20, which is connected to the slider 7 through a screw nut. One end of the screw 20 is connected to a DC motor. Therefore, the screw conveyor device 19 can drive the hydraulic cylinder 8 and the suction cup device 6 to move.
[0025] The outer ring of the pressure bearing 13 is fixedly connected to the first gear 15, and the positioning column 21 is fixedly connected to the stepper motor 14. The output shaft of the stepper motor 14 is fixedly connected to the second gear 17, so the stepper motor 14 can drive the suction cup device 6 to rotate.
[0026] The suction cup device 6 is equipped with an electric screwdriver 9 and a material suction device 10. The electric screwdriver 9 is located in the upper half of the suction cup device 6, and the material suction device 10 is located in the lower half of the suction cup device 6. Therefore, after the suction cup device 6 rotates, the screw placement and tightening operations in each half can be completed in half.
[0027] The lower part of the suction cup device 6 is provided with a winding disc cover 1, the lower part of the winding disc cover 1 is provided with a winding disc cylinder 2, the upper part of the winding disc cylinder 2 is fixedly connected with a positioning block 3 and a central cylinder 4, the winding disc cover 1 is provided with a locking hole that cooperates with the positioning block 3 and the central cylinder 4, the winding disc cover 1 is provided with a central hole that cooperates with the central cylinder 4, and the winding disc cylinder 2 is provided with a screw hole 5.
[0028] The electric screwdriver 9 has a motor inside, which can drive the screwdriver bit 91 to rotate and thus tighten screws. The suction cup device 6 has a through hole 18. The suction device 10 includes a negative pressure air pump 11. The lower part of the negative pressure air pump 11 is connected to the suction head 16. After the negative pressure air pump 11 generates negative pressure, the suction head 16 can pick up the screw.
[0029] A camera 12 is installed on the suction cup device 6 for positioning by controlling the perspective or by manual alignment, and a slider 7 is fixedly connected to the upper part of the hydraulic cylinder 8.
[0030] Working Principle: The lead screw conveyor 19 is a key component of the entire system. Through the precise engagement of the lead screw 20 and the lead screw nut, it achieves accurate control of the slider 7. Since the hydraulic cylinder 8 is fixed to the slider 7, when the DC motor drives the lead screw 20 to rotate, the lead screw nut converts the rotational motion into linear motion, thereby driving the slider 7 and its hydraulic cylinder 8 to move horizontally. The piston rod of the hydraulic cylinder 8 is fixedly connected to the positioning column 21, meaning that as the hydraulic cylinder 8 moves, the suction cup device 6 also adjusts its position to adapt to the needs of different workstations.
[0031] The suction device 10 includes a negative pressure air pump 11 and a suction head 16 for accurately picking up screws from the feeding area. When the suction head 16 contacts the screw, the negative pressure air pump 11 activates, generating sufficient suction force to firmly hold the screw on the suction head 16. Subsequently, the screw conveyor 19 moves the suction cup device 6 to a designated position above the winding reel cover 1 according to a preset program. At this point, the suction head 16 releases the screw, allowing it to fall accurately into the screw hole of the winding reel cover 1. This process ensures precise screw positioning, laying the foundation for subsequent tightening operations.
[0032] like Figure 5 The electric screwdriver 9 shown is located in the upper half of the suction cup device 6, and the suction device 10 is located in the lower half of the suction cup device 6. Therefore, after the suction cup device 6 rotates, the screw placement and tightening operations in each half can be completed in half.
[0033] The electric screwdriver 9 completes the screw tightening, realizing the connection between the winding reel cover 1 and the winding reel cylinder 2.
[0034] Once the screw is in place, the electric screwdriver 9 comes into play. The electric screwdriver 9 is mounted on the suction cup device 6 and extends downwards through the through hole 18. Its internal motor drives the bit 91 to rotate, applying appropriate torque to screw the screw into the screw hole 5, thereby firmly fixing the winding reel cover 1 to the winding reel cylinder 2. This design not only improves assembly efficiency but also ensures the tightening quality of each screw, avoiding errors or loosening problems caused by manual operation.
[0035] To further improve assembly precision, the suction cup device 6 is designed to rotate freely around the positioning post 21. Specifically, the pressure bearing 13 allows the suction cup device 6 to make fine adjustments to its rotation while maintaining stable gripping, based on the power provided by the stepper motor 14 and the transmission relationship between the first gear 15 and the second gear 17. This enables the rapid adjustment of the position of the winding reel cover 1 even in complex assembly environments, ensuring perfect alignment with the winding reel cylinder 2, ultimately achieving high-precision and high-quality assembly results.
[0036] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
